Joule to Hertz Calculator
Convert energy from Joules (J) to Hertz (Hz)
Note: The conversion from Joules to Hertz is based on the formula:
Frequency (Hz) = Energy (J) / Planck’s constant (h) = J / 6.62607015 × 10⁻³⁴ J·s
How to Relate Joules to Hertz
Joules (J) cannot be directly converted to hertz (Hz) with a simple numerical factor because joules measure energy and hertz measures frequency—different physical quantities. However, they connect in quantum mechanics through the Planck-Einstein relation, E = hf, where energy in joules relates to frequency in hertz via Planck’s constant.
Energy-Frequency Relationship
Quick Trick: To find frequency from energy, use f = E/h!
Know the Relationship
Frequency is defined as the number of occurrences of a repeating event per unit time. In terms of energy, when energy is associated with a frequency, it can be described using Planck’s constant. This relationship is fundamental in quantum physics!
For example, if you have 1 joule of energy, the frequency can be calculated using the formula f = E/h.
The general relationship is:
Energy (J) = Planck’s constant (h) × Frequency (Hz)
Let’s Solve One Together!
Imagine you have an energy measurement:
- We measured: 1 joule
Here’s how we figure it out:
1. Take our formula: f = E/h
2. Put in E = 1 joule and h = 6.626 x 10-34 J·s
3. Calculate f = 1 / (6.626 x 10-34)
4. f ≈ 1.51 x 1033 hertz
Answer: 1.51 x 1033 hertz
What Do These Terms Really Mean?
Joule (J) – A Unit of Energy
Joules (J) are a standard unit of energy in the International System of Units (SI). Here’s what you need to know:
- Used to measure energy, work, or heat.
- 1 joule is the energy needed to move a force of 1 newton over 1 meter.
Hertz (Hz) – A Unit of Frequency
Hertz (Hz) are a standard unit of frequency in the International System of Units (SI). Here’s what you need to know:
- Used to measure frequency in cycles per second.
- 1 hertz is equal to 1 cycle per second.
